floor prevents so great an amount of water flowing over the saine, a large part ot the excess water being carried off by the culvert and the posts 3 on the lower` side of the structure would serve to arrest and prevent vehicles or live stock from being washed awa 1. In concrete construction, a culvert, road bed formed t-hereover and having` its sides and floor sloping` downward :trein the banks of the stream to a pointy above the culvert, the lower portionot the road bed at the center thus a'tl'ording an overflow outlet for the water and relievingl the device oi thel strain to which it would be subject were there no outlet` for the water except the culvert. p

2. In concrete construction, a roadway formed with its sides and floor sloping downwardly from the end toward the center. a pipe passing laterallv under said roadway, and means for late/rally bracing;- the roadway. r

3. In concrete construction, a culvert, a, concrete road bed passing thercover and curved downwardly from the. ends toward the center to provide an overflow outlet for water not carried oft by the culvert, tapering posts forrn'ed thereon for bracing the of said posts.

l. in combination with a eoncaved concrete roadbed sloping downwardly from both ends toward the center and providing;` an overflow outlet for water not otherwise carried ol', a pipe passing laterally-therethrough, tie and brace rods secured therein. and pillars formed thereon havingr broad bases taperingY toward the top, v'for bracing the roadbed against lateral strain.
